    oops sorry yea that would help.

    The car is a 96 A3 in ming blue. she hasnt had the car from new sadly she got it about 3 years ago and it has no recorded accident damage but it was a city car before she had it so its possible its been bashed about a bit.

    My initial gut feeling is that it is clear coat failure; the way the patch blends in from the left to a sharp edge on the right is suggestive of too much clear removal by machine. A proper visual inspection and paint depth readings is the only way to properly tell. The paint on Audi wings always seems to be much thinner than on other panels, and we have seen readings as low as 50 microns in the past, which means there isn't always a lot of clear to play with, and even less so if the car has been machined multiple times in the past. The paint transfer supports my feeling; once you go through the clear the pigment layer is reached and transfers onto the pad. However, without seeing the car in the flesh I can't confirm any of this. Based on your method and products clear failure shouldn't have happened, but without knowing the full history of the car and in particular the quality of previous repairs then this type of thing can happen. It might be worth asking on Detailing World if there is anyone in your local area who owns a paint gauge who would be willing to take some readings for you - that would firm up the answer. :)

    thanks for the reply it looks like my worse fears have come true of it being a clear coat failure.....ime even more pissed off as its my mums car and not mine.

    Dont sound very good about the paint being thinnner on the wings especially from audi. Mind you it could be a lot worse as its on the side of the car with the huge key mark down the side, i dunno if my mums going to bother getting it all sorted as yet.

    Thanks for ya advice appreciate it.
